Abstract
The heats of mixing of aqueous solutions of monomethylurea, urea and thiourea were determined at 298.15 K and the excess enthalpies obtained were expressed in terms of pair- and triplet-interaction coefficients. The validity of the empirical rule: hij2 ≈ hii hjj, relating the self- and cross-interaction coefficients, was tested for the solutes under examination, for which both hii, hjj < 0.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
